To all whom it may concern;

Be it known that we, VIc'ron E. .EKTROM and THOMAS G. Bdmor'raiv, bothcitizens of the United States, and residents of Tomahawk, in the countyof Lincoln and State of "Wisconsin, have invented a new and ImprovedElectric Cigar-Lighter, of which the following is v a full, clear, andexact descriptiou. I V

This invention relates to a new and 1mprovedcigar lighter, of a type inwhich the. heat of ignition is obtained by passing a cur rent throughunexposed resistance wire bent so as to offer a plurality of juxtaposedlengths within a small compass. It has been tound with such electriccigar lighters of this type which are now on the markehthat aconsiderable quantity of expensive platinum wire, which is also readilybreakable, is necessary in order t0 obtain the required heating surfacewhen connected to the-ordinary electric light circuit which runs at onehundred and ten volts. y

It is the object of this invention to so construct a cigar lighter thatthe current can be transformed or stepped downto a lower voltage andincreased amperage, enabling the use of a much coarser and strongerwire, of entirely less expensive material, which will offer a greaterheating surface, and will come to the glowing point in the shortestpossible space of time. i

A further ob ect of this invention is to provide a device. whiclpwill,be simple in construction, inexpensive to manufacture, strong, durable,and readily accessible for the purpose of renewing the parts.

These and turther-objects together with the construction and.combination of parts, will be more fully described hereinafter andparticularly set IOItll in the claim,

REIEGITlIIg more particularly. to the separate parts in Fig, 1 isillustrated the form which is adapted tobe set on a shelf or cigar case,and consists of a base 1,-a body 2 and a lighting head 3.

I i In the form illustrated in Fig. 2, the

lighter is suspended from a suitable support, in juxtaposition to acigar counter or the like, by means of electrical conducting wires,indicated at 4., and consists also of a body portion 2 and a lightinghead 3. Arranged in front of the lighter, there is provided an opening5, through which a cigar is to be inserted when it is desired toiight'the same. Arranged in back ofthis opening 5,.tliere is provided anon-conducting block 6, secured to which is provided an exposedresistance wire 7 of any suitable material, such as a" pliable alloy.This resistancewire 7 is bent back-and forth along the taco of the block6, so as to ofi'er a plurality of linlrsthereot in close and yet spacedjuxtaposition, so as to offer the greatest amount of glowing sur- Theends of the resistance wire '7 are connectedflto suitable terminalscrews 8' and 9, which in turn extend to the secondary winding 10 of atransformer 11, which is preferably located within the cigar lighter,

It will be seen by reference to Fig. 5 that I a secondary circuit isformed through the resistance 7, the secondary coil 10, and thewiresronnecting them together. The secondary winding 10 is arranged inclose juxtaposition to a primary winding 12 of the transformer 11. Thisprimary winding 12 is connected by, wires 13 and 1d to a suitable sourceof electricity, indicated by the socket 15. This circuit through thewires 13 and 14 and .the primary winding 12 is provided with a break at16.. The ends of the wires at the break 16 are provided with contacts 17and 18, which are adapted to be brought into engagement by means of apush button 19. .The latter extends out 2 through the body of thelighter in any convenient position, where it will be readily accessibleto the user. The contact 18 is preferably made of a springy material, so

that when the pressure onthe button 19 is released, itwill automaticallyspring out of engagement. with the contact 17.

The utility of the device will be readily understood from the abovedescription. When it is desired to light a cigar, the butt end isinserted through the opening 5 and juxtaposed to the resistance wire 7'.The button 19 is then pressed, so that a circuit is completed through.theprimary coil 12, thereby causing a currentto pass through thesecondary coil 10 of the transformer 11. This transformer 11 may becontrolled in any suitable manner to make and break the circuit, so asto. have a constant impulse of current through the secondary winding 10.The current passing through the secondary circuit will cause theresistance wire 7 to glow, thereby enabling theuser to light his cigar.Inasmuch as-the. voltage of the current can be reduced inamount by thecharacter of the windings in the transformer 11, it will enable the useof a'coarse and in- GXPGIlSlVQT$1St3I1CG w re, which will last a longtime, and which, when worn out, can

'be renewed at little or no expense. As soon as the pressure is relievedon the button 19, the primary circuit is disconnected, thusdiscontinuing the flow 'of current through thesecondary circuit;

While we have showntwo embodiments tions and alterations whichwe maymake within the scope of the appended claim.

Having thus described our invention, we

claim as new and desireto secure byLett'ers Patent I In a cigar lighter,the combination with a body having a, plurality of cavities therein,

of atransformer located in one of said cavities, a lightin head locatedonthe face of said body an transformer, contacts in another of saidcavities within said body, normally out of engagement with each otherand connected with said transformer, and a push-button Within saidlast-mentioned cavity. and adapted to bring said contacts intoengagement, and. projecting above the surfaceof said body, whereby itmay be readily operated, said lighting head comprisin an insulatingblock, a resistance wire bent ack and forth along the face of saidblock, terminal screws connected to said insulating wire, and a coverplate for said block, having an opening therein adapted to permit accessto said resistance wire. a In testimony whereof we have signed our namesto this specification'in the presence of two subscribing witnesses.
